Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.

Benchmark anchor. The T3 technical header governs the scored identity; contradictory S3/S4 labels in the battery table remain disclosed. Scored model: EK90 HS5-20K-T3-X · checked 2026-08-26. Evidence.

Strong evidence coverage

21 of 21 scored criteria link directly to a published source.

Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.
